I read about Lionel Messi according to the personal's opinion of the former couch of FC Barcelona, Quique Setien, He said that Lionel Messi is a naughty player because he is difficult to be controlled. This is not true at all. Messi is a humble man in my opinion personally. He is not a man to talk too much if he though the thing is not important to discuss.
Although, Setien recognized that Messi is the best player in the world , but he said that Messi was rare to talk in changing room.
Ronald Koeman is not agree to Setien. A new couch from Holand said that Messi is a polite and wise man. He always want to win every games, said Koeman.
I think Setien can not show his best during managing FC Barcelona and he regret it but he has no chance to come back to Camp Nou to do the best for players.
For me, Lionel Messi is GOA, Greatest of All Times.
